Question

solve it.....genious ​

Answer 1

Answer:

Given that set A is the set of prime number less than 10 which means

A={2,3,5,7}

also given that Set B is set of odd numbers less than 10 which means

B={1,3,5,7,9}

Now LHS of given expression:-

n(A U B)=6

The 6 terms are 1, 2, 3, 5, 7, 9.

And RHS :-

n(A)+n(B)-n(A n B)

=4+5-3 [n (A n B) are 3, 5, 7)]

=6 .

So, required result is proved both sides prove to be equals to 6 so both sides are equal to each other.

Answer 2

Answer:

Step-by-step explanation:

Given that set A is the set of prime number less than 10 which means

A={2,3,5,7}

also given that Set B is set of odd numbers less than 10 which means

B={1,3,5,7,9}

Now LHS of given expression:-

n(A U B)=6

The 6 terms are 1, 2, 3, 5, 7, 9.

And RHS :-

n(A)+n(B)-n(A n B)

=4+5-3 [n (A n B) are 3, 5, 7)]

=6 .

So, required result is proved both sides prove to be equals to 6 so both sides are equal to each other.
